Field experiments were carried out to study the interactive effects of plastic mulch and tillage method on yield and quality of tomato (Lycopersicon esculentum) during 2007 and 2008 growing seasons. Mulch levels in the study were plastic-mulching (PM; black plastic mulch) and no-mulching (NM) and tillage treatments were conventional tillage (CT; moldboard plowing + two passes of disk harrowing)...

To investigate effects of putrescine (Put) and humic acid (HA) on fruit yield and physiological attributes of okra (Abelmoschus esculentus L. 'Kano') under water deficit stress, a field experiment was conducted in split plot based on a randomized complete block design with three replications. Plants were exposed to three different irrigation regimes (33%, 66% and 100% ETc) and were treated with...

This study was carried out on olive trees cv. Amygdalifolia, to investigate the effect of spraying potassium nitrate, KnO3, and zinc sulfate, ZnSo4, on the fruit weight, dimension and volume. The plants were sprayed with 0, 0.5, 1.0 and 1.5% KnO3 and 0, 0.25, 0.50 and 0.75% ZnSO4 and their combinations in August about halfway through the fruit growth period. The highest fruit weight was observe...

The aim of this study was to determine the most suitable shaking frequency and amplitude for shake harvesting lime fruit (C. aurantifolia). A tractor mounted limb shaker with adjustable shaking frequency and amplitude, powered by the tractor power-take-off shaft was designed and developed for this study. The rotating input power was transmitted to the shaker flywheel through a multiple sheave v...

Morphological studies showed that tree shape in Bitter sweet orange and Yuma citrange was spheroid with spreading growth habit and wide branch angle. Leaves were simple with dark green color, medium size and brevipetiolate in Sour orange while Yuma citrange had trifoliate leaves with medium and green color. Bitter sweet orange had the highest leaf lamina length (10.4 mm) than other rootstocks. ...

Heterogeneity in fruit quality (size and taste) is a major problem in pineapple production chains. The possibilities were investigated of reducing the heterogeneity in pineapple in the field by pruning slips on selected plants, in order to promote the fruit growth on these plants. Slips are side shoots that develop just below the pineapple fruit during fruit development. Two on-farm experiments...

Fruit juices each have very distinct organic acids profiles that can be used as fingerprints for establishing authenticity. A method has been developed, optimised and validated for measuring by capillary electrophoresis citric, isocitric, malic and tartaric acids as authenticity markers in orange juices, without any sample treatment other than dilution and filtration. Final conditions were phos...

longevity of osseointegrated implants are intensely influenced by biomechanical factors. control of these factors prevents mechanical complications, which include fracture of screws, components, or materials veneering the framework. in this study, the impact of length and threads pitch of dental implants on the stress distribution and maximum von mises stress in implant-abutment complex and jaw...
